Check Digit Verification of cas no

The CAS Registry Mumber 117605-22-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,7,6,0 and 5 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 117605-22:
(8*1)+(7*1)+(6*7)+(5*6)+(4*0)+(3*5)+(2*2)+(1*2)=108
108 % 10 = 8
So 117605-22-8 is a valid CAS Registry Number.

Studies on Angiotensin Converting Enzyme Inhibitors. 4. Synthesis and Angiotensin Converting Enzyme Inhibitory Activities of 3-Acyl-1-alkyl-2-oxoimidazolidine-4-carboxylic Acid Derivatives

Hayashi, Kimiaki,Nunami, Ken-ichi,Kato, Jyoji,Yoneda, Naoto,Kubo, Masami,et al.

, p. 289 - 297 (2007/10/02)

(4S)-1-Alkyl-3-acyl>-2-oxoimidazolidine-4-carboxylic acid derivatives (3) were prepared by two methods.Their angiotensin converting enzyme (ACE) inhibitory activities and antihypertensive effects were evaluated, and the structure-activity relationships were discussed.The dicarboxylic acids 3a-n possessing S,S,S configuration showed potent in vitro ACE inhibitory activities with IC 50 values of 1.1x10-8-1.5x10-9 M.The most potent compound in this series, monoester 3p, had an ID 50 value of 0.24 mg/kg, po for inhibition of angiotensin I induced pressor response in normotensive rats and produced a dose-dependent decrease in systolic blood pressure of spontaneously hypertensive rats (SHRs) at doses of 1-10 mg/kg, po.
